Firstly, you will have to assemble Muscle BioAmp Shield v0.3 as we provide it as a DIY Kit.

After completing the assembly, Muscle BioAmp Shield v0.3 should look like this:

As Muscle BioAmp Shield v0.3 is an Arduino Uno Shield, you can directly stack it on top of it as shown in the picture below:

BioAmp Cable is an electrode cable that comes with 3-pin JST PH 2mm connectors on one side and snappable connectors on the other side as shown in the picture below:

You can connect this cable to Muscle BioAmp Shield v0.3 via a 3-pin JST PH 2mm connector. 

You can detect EMG signals from your muscles either using gel electrodes or Muscle BioAmp Band that comes with dry electrodes.

The snappable connectors on the BioAmp Cable can be snapped on both the gel electrodes as well as the Muscle BioAmp Band easily.

Connect your Arduino Uno to the laptop using the cable
